So much better than blocking extensions! I eventually override blocking entensions because i want to use the blocked site (stoping altogether is not an option), with Intention I can use it but before using it stop, think what I want to do, and set a timer. That's soo much better!

does the job perfectly !!

One of the best and simplest blocker add ons I've ever used. Its really helped me use social media in moderation rather than quitting cold turkey (which never works for me)

It works very well for me

無限に時間をとっていく、ネットサーフィンという無駄な時間から、私たちを解放してくれる理想的な拡張機能です！
スマホ版も欲しい！！！ご検討よろしくお願いします！

Really works and is very effective. Need to have this extension on my android phone as well.

Thanks

I tried at least 5 productivity add ons and this one is the best! Minimalistic and powerful at the same time

Best "focused browsing" addon by a mile, the possibility of getting periodically reminded you may have been sucked into the vortex of a distracting website is killer. This addon should be integrated in firefox so as to fullfill its vision of a a free browser which puts the user first and defends it from destructive corporate interests. @DK you should really try to get in touch with the firefox team, opensourcing this addon (as well as extending your feed-blocking addon) and in general working on a "firewall" against intrusions and distractions on the web should be a top priority of the free software movement.
